ing to be a full, clear, and exact description oi the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

This invention relates to book binding and particularly to books havingremovable covers.

An object of this invention is to provide a book having a removablecover that will have a flat opening.

A further object of this invention is to provide a bank book easilycarried in the pocket, of simple and cheap construction, that will havea removable cover, and that will lie at when open."

A further object of this invention is to simplify and cheapen the costof production of such a book.

With these and other objects in view, as will become readily manifest tothose versed in the art, the invention consists in the means and indetails and arrangement of the elements thereof as more particularlydescribed in the following speciication relative to the embodiment or'the invention illustrated in the accompanying drawings, in which- Figure1 is a perspective view of my book showing the cover partially removed.

Fig. 3 is a longitudinal section at 3 3 of Fig.1, v

The book leaves A are attached to the leather cover B by the tongue Csliding in the flanged groove D. The leaves A are aixed to the tongue Cby stitching, as at 1. The grooved member D is al'hxed to the leathercover B by clips pressed into'the leather cover B, as shown at 2. TheseVclips are stamped from the stockof the grooved member D. A

yIhe grooved member D, which is a single piece of sheet metal, isflanged, as shown at 3, and an abutment formed at one end, as shown at4. On the other end is a lip 5 which may be turned upto keep the tongueC from coming out after having once been inserted.

By reason of the leaves A being superimposed upon each other andstitched immediately upon the at tongue C it is obvious that when openthe book will lie flat.

IVhat I claim is:
